Wayfair | Software Engineer (L3) | Bangalore | Rejected

Round 1: Online Assessment (OA) Round

Questions: The OA consisted of 2 coding questions in 60 minutes (1 easy, 1 hard).
Link to the OA question
The first question was challenging. I used BFS but could only get 12/15 test cases correct.

Candidate's Approach

I implemented a BFS algorithm to solve the first question but faced challenges that led to only 12 out of 15 test cases passing.

Interviewer's Feedback

No feedback provided.


Round 2: Coding Round

Questions: Link to the question: Coupon category
I had seen this problem before, which helped me complete it successfully with all follow-ups. Without prior exposure, I don't think I would have been able to finish it on time.

Candidate's Approach

I leveraged my prior experience with the problem to solve it efficiently and address all follow-up questions.

Interviewer's Feedback

No feedback provided.


Round 3: Low-Level Design (LLD) Round

Questions: The problem was bike rental shop question.
I was well-prepared, but the interview was chaotic due to the interviewer being new and a senior member shadowing, which led to confusion.

Candidate's Approach

I aimed to cover key areas like API design, class structure, and database schema but struggled due to interruptions and conflicting expectations from the interviewers.

Interviewer's Feedback

No feedback provided.


Round 4: High-Level Design (HLD) Round

Questions: The problem was a mobile check-in system.
I struggled with time management and was only able to cover the basic components and requirements.

Candidate's Approach

I attempted to address the basic components of the system but failed to cover advanced topics such as rate limiting, caching, and analytics due to time constraints.

Interviewer's Feedback

While I performed well in the coding round, my performance in LLD and HLD was not up to expectations. Had I done better in any one of these design rounds, I could have cleared the interview.
